Thiago TeixeiraYale ENALAB - http://www.eng.yale.edu/enalab6 Correlating Gait Signals from Asynchronous Sources  Sample-oriented methods are unsuitable for WSNs: (eg. Pearson's corr. coefficient, mutual information)  Fail given time synchronization offsets (or must slide one of the signals and recalculate)  Require a large number of samples to converge  Requires resampling/interpolation if signals have different sampling frequencies and/or phases  We can do better, using gait frequency and phase…
